PPM-8012-14 JK WELD ON HD FRONT LOWER
CONTROL ARM BRACKETS, STOCK TUBE

Version 1

GENERAL NOTES:

• These instructions are also available on our website; www.synergymfg.com.

Check the website before you begin for any updated instructions and additional
photos for your reference.

• These heavy duty lower control arm brackets are meant to replace the original

brackets on the stock axle tube

• The installation of this bracket requires the complete removal of the stock lower

control arm bracket with a sawz-all and cut off wheel or plasma cutter or oxy­acetylene torch. The new brackets must be welded to the axle tube. An
experienced fabricator/welder is recommended to properly install this bracket.

• It is recommended to completely remove the front axle from the vehicle. You can

install these on the vehicle but it is much more difficult.

1. Remove the lower control arms.

2. Completely remove the factory control arm brackets and grind smooth.

3. Break the lower control arm brackets apart. There is a different left and right bracket.
When you position them to the axle tube, they should angle out so the control arms
are wider at the frame then on the axle. Once you determine which the right and left,
position them on the axle tube.

4. Start with the driver side bracket. Position the bracket as shown, with the inner edge
against the cast diff housing.

5. The bottom edge should be level or back edge vertical when the pinion is level or
diff cover surface is vertical. Tack weld in place.

POSITION THESE TWO PICS SIDE BY SIDE

6. Position the passenger side bracket opposite. The easiest way is to measure from the
machined edge adjacent to the weld on the inner C. Measure the driver side then
make the passenger side bracket the same dimension. The dimension should be close
to 5 ¼ to the outside edge of the new lower control arm bracket. Tack weld into
place.

7. Fully weld the lower control bracket to the axle tube. Weld along the front edge and
sides. Wrap the weld around the back edges at least ½ along the inner edge. You
will have to weld the inner edge on the driver side bracket that is adjacent to the diff
housing.

8. The lower control arm brackets have two mounting positions. The lower hole is the
stock location; you can move the lower control arms to the upper hole and trim the
bottom for more ground clearance.
